George Zimmerman -- acquitted by a Florida jury over the death of Trayvon Martin -- was involved in a shooting in Lake Mary, Florida, on Monday, police spokeswoman Bianca Gillett said.
Zimmerman apparently suffered a minor gunshot wound, WESH-TV reported, citing the police chief.
The shooting is under investigation, but it appeared to be some type of road rage incident, Gillett told CNN.
Police said there were no fatalities in the shooting and said the department would not release additional information until a briefing planned for Monday afternoon.
It is the latest headline-grabbing incident for Zimmerman since his acquittal in July 2013 on a murder charge in the death of Martin, a 17-year-old African-American.
Zimmerman fatally shot Martin on February 26, 2012.
On that day, Zimmerman, a neighborhood watch captain in Sanford, Florida, called 911 to report "a suspicious person" in the neighborhood.
He was instructed not to get out of his SUV or approach the person, but Zimmerman disregarded the instructions. Moments later, neighbors report hearing gunfire.
